20%\u201330% of total energy consumption in the global industrial sector is lost in the form of low-grade waste heat. The 100\u2013200 \u25e6C exhaust waste heat generated by the pyrolysis process of waste tires has a remarkably high recovery potential, but its organic Rankine cycle (ORC) system has difficulty in optimizing efficiency due to multi-parameter nonlinear coupling. This study proposes a hybrid optimization framework that integrates a fractional factorial Taguchi Design of Experiments (DOE), a two-layer Stacking Ensemble Learning architecture (SVR+ANN), and a Genetic Algorithm (GA), aiming to solve the inefficiency and poor local convergence of traditional trial-and-error or isolated optimization methods in engineering practice. The results show that by systematically regulating the evaporation temperature, condensation temperature, working fluid mass flow rate, and expansion ratio, the thermal efficiency of the ORC system has significantly improved from the baseline value of 13.2% to 26.9%. In addition, a comprehensive environmental assessment framework with strict system boundaries was introduced. Considering auxiliary energy consumption and working fluid global warming potential (GWP), the evaluation showed that the optimized system could reduce net emissions by 92.5 kg for every ton of waste tires processed based on localized grid emission factors. Experimental verification, backed by an independent validation dataset and uncertainty analysis, shows that the prediction deviation is less than 0.2%, confirming the excellent generalization capability, robustness, and reliability of this framework in industrial low-carbon transformation practice.<\/p>\n\n\n\n
